[Also in Division B2] In the production of a ferrite by milling, shaping, presintering, re-grinding, shaping, and finally sintering, the re-grind is effected by using a diamond studded grinding wheel. The diamond grains may be held in a binder of bronze or rubber on the upper face of a horizontal wheel, which may be immersed in a liquid, e.g. water or alcohol, and the presented bodies may be pressed on to the said face by weights. The starting materials may be oxides, oxalates, or carbonates, which may initially be ground and mixed in a ball mill in liquid.

Filed: 1968-09-27
Abstract: 1,217,879. Control of D.C. motors. SEVCON ENG. Ltd. 26 Sept., 1969 [27 Sept., 1968], No. 46046/68. Heading H2J. A float is disposed in a reservoir tank of a battery-powered industrial truck, the tank providing a source of hydraulic fluid for a mastextending ram. Fluid is supplied to the ram by a pump driven by a D.C. motor which is energized from the battery in dependance of the mark-space ratio of a pulsing controller. Movement of the float varies the mark-space ratio to limit the motor speed thereby achieving an optimum tilt speed for the height of the load. The float movement is also employed to vary the mark-space ratio of a pulsing controller for the traction motor. When the mast is being extended, the float falls to increase the resistance of associated potentiometers and to reduce the frequency of firing pulses for thyristors forming part of the pulsing controllers. The motors may be of the series or shunt types and adapted for field or armature control. A modification employs variable pulse-width controllers having main and commutating thrysistors.

Title: System and method for operating a steam turbine with independent overspeed protection
IPC: F01D21/02
Filed: 1972-10-06
Abstract: 1411814 Steam turbines WESTINGHOUSE ELECTRIC CORP 6 Oct 1972 [14 Oct 1971] 46125/72 Heading F1T A steam turbine plant has an overspeed protection arrangement comprising three separate speed sensing systems and logic circuitry such that if any two of the sensing systems indicate a potential or actual overspeed condition then turbine steam flow control valves are closed. In Fig 1B a nuclear heated steam generator 102, 103 supplies steam through stop and governor valves 106, 108 to an H.P. turbine 110 and thence through a reheater (116) Fig. 1A (not shown),  stop and interceptor valves (120, 118) to L.P. turbines (112, 114). The turbines drive an electric generator (122). In addition to the speed and other sensors controlling the steam valves during normal operation the plant includes three independent speed sensors 124-1, -2, -3 each with an associated check circuit 138, 140, 142. Each of the latter includes Fig. 2 (not shown), a comparator (210) to compare the sensed speed with an overspeed reference, e.g. 111% of synchronous speed, and a delay arrangement (220, 222) to sense any abrupt change in turbine speed, together with testpoints to check operation of the circuitry. Check circuits 138, 140, 142 are connected via relays 146, 148, 150, 152 &c. to a logic circuit 144 which includes duplicate AND-gates (172, 176) Fig. 4 (not shown), which operate to close the steam flow valves if a minimum of two check circuits emit signals indicating actual or potential overspeed or failure of the sensing system power supply. Thus it is possible to check operation of any one of circuits 138, 140, 142 during plant running without reducing overspeed protection. The steam flow valves 106, 108, (118, 120) are positioned by hydraulic actuators 130, 132, (136, 134) respectively and when the AND-gates (172, 176) emit overspeed signals solenoids 50, 51 operate to open valves 506, 508, Fig. 5, to cause rapid dumping of operating oil from each actuator cylinder 500 into a receiver 510, the steam valve thus closing under the action of spring 518. Receiver 510 is of heavy steel and has an associated shield (524, 526) Fig. 6 (not shown), to protect valves 506, 508 from turbine fragments. The receiver may include a blowout disc (528). Normal running of the plant may be controlled by a digital or analogue computer which may also be used to perform the function of check circuits 138, 140, 142 and of logic circuit 144.

[Also in Division F2] Two parallel mixer shafts 33, 34 are rotated by cranks 74, 75 coupled by a triangular member 73 (see also Fig. 6 not shown) to a drive crank 65; the cranks are V-shaped so that they nest, and have a throw greater than the distance between shafts 33, 34. Materials are fed in by intermeshing screws 38, 39 and the mixer shafts have four-lobed mixing members 42, 43 (see also Fig. 4 not shown) arranged helically round the shafts, and having a 45 degree phase difference between the shafts so that the members 48, 49 wipe each other and the walls of the chamber, which is formed as two intersecting cylinders. The members 42, 43 may also have helically formed edge surfaces. There are also discs 48, 49 which have the same cross-section as the cylinders and are spaced alternately on shafts 33. 34 to provide a sinusoidal path through the apparatus. The materials are then forced through narrow annular passages 22a, 22b formed between conical surfaces of an internal flange 23 in the endplate 22 and those of members 50, 51 and 54, 57 on the mixer shafts: the members 50, 51 are eccentric. The sizes of the passages may be altered by axial adjustment of the end plate 22 by jacks 28, 29, and of the members 54, 57 on their screw-threads. The mixer housing consists of two halves (3, 4 Fig. 1) pivoted to one another and to the base, and having passages for a cooling or heating medium.

A device for feeding the rod into the chamber comprises a clamp 62, (66), Figs. 6 to 9 (not shown), adapted to grip the rod and advance with it towards the chamber upon actuation of a trigger 82 by the operator, and to release the rod and return to a rest position upon release of the trigger. Alternatively, an electric motor (not shown), with a drive-shaft and wheel may be used, with means being provided to force the wheel and rod into inter-engagement to advance the rod into the melting chamber.

Abstract: 1275772 Controlling feed of engine exhaust gas to purifying system TOYO KOGYO CO Ltd 26 Sept 1969 [28 Sept 1968] 47478/69 Heading B1X [Also in Division F1] An I.C. engine exhaust gas purifying system includes a passage 3 Fig. 1 branched into a reactor passage 7 and a by-pass passage 8 and a jet stream from a control nozzle 9 is influenced in accordance with the proportion of unburnt component in the exhaust gas so that when the proportion is low the gas passes through the by-pass and when the proportion is greater the gas passes through the reactor. When the throttle valve 5 is closed the inlet vacuum acting on diaphragm 14 opens valve 12 and closes valve 13 so that air pumped from pump 10 passes through jet 9 to deflect the gas through the reactor passage 7. When the throttle valve 5 is open valve 12 is closed and the air passes to atmosphere through the open valve 13. The reactor may have a catalyst for reacting the unburnt component with secondary air or may be a substance to absorb an unburnt component. In a modification the air passing valve 13 (when open) is passed into the exhaust gas passage downstream of the exhaust valve. In another modification the reactor passage (7), Fig. 4 (not shown) and by-pass passage (8) are symmetrically offset from the exhaust passage and the exhaust gas stream is controlled by opposed jets (9a, 9b). In a further modification the inlet of the control jet passage (20), Fig. 5 (not shown) is inclined to the exhaust gas stream upstream of the control jet (9), the reactor passage (7) being in lime with the exhaust gas passage (3). In another embodiment air from pump 10, Fig. 6 is directed either to control jet 9 or atmosphere by vacuum-actuated valves 21, 22 controlled by solenoid valves 25, 26, one or the other of which is energized by relay 30. The latter is actuated in response to signals from intake manifold vacuum 35, coolant temperature 36, lubricant temperature 37, exhaust gas temperature 38, engine speed (by pulses from coil 41) and vehicle speed (by signals from generator 39).
